Porsche 911 Puts Turbos on its Turbos

Distinct from the turbo-but-not-Turbo Porsche 911, the new high-performance models come to market with either 540 or 580 horsepower, depending on which version of the 3.8-liter, twin-turbocharged flat-six engine you choose.

Both figures count as a 20-horsepower bump over the last Turbo/Turbo S, allowing both models to hit 100 in under three seconds – 2.9 and 2.7 seconds, respectively – and in the case of the S, on to a 321-plus-km/h top speed.

This capability will not come cheap, of course. Before so much as dipping a toe into Porsche's notoriously deep options catalog, the base Turbo will demand a $160,195 check. That's awfully spendy, and things don't improve as you climb up the range. The cabriolet adds $12,300 to that, while the S starts at $189,095. Going topless in the Turbo S will require $201,395. We had no trouble building a Turbo S Coupe up to $211,000 without adding some of the more obnoxious options, like the $1,720 leather air vents.
